[PATCH] proc: fix of error path in proc_get_inode()

This patch fixes incorrect error path in proc_get_inode(), when module
can't be get due to being unloaded.  When try_module_get() fails, this
function puts de(!) and still returns inode with non-getted de.

There are still unresolved known bugs in proc yet to be fixed:
- proc_dir_entry tree is managed without any serialization
- create_proc_entry() doesn't setup de->owner anyhow,
   so setting it later manually is inatomic.
- looks like almost all modules do not care whether
   it's de->owner is set...
